Mitosis: How One Cell Becomes Two

We know that we are made of cells. But we start out as just one tiny little cell in the womb. How does that become enough cells to look like a baby? And how does that baby get enough cells to become an adult? The answer is mitosis! This is how cells divide to produce new cells with all the DNA for that organism. How does this work? Let's find out!

I like to watch these the night before my teacher discusses that topic in class.
It makes the note taking and information processing so much easier because you feel like you have an overall / general idea of where it’s going. It also helps me understand any reading we have for the topic.

Professor Dave is saving my life since my first year at science school. Thanks !

[shylalang]

So glad I found this channel.. I have a exam on Tuesday and for once this entire semester I actually feel confident in the test

[taylorbarnett]

I would like my diploma now, professor Dave university. 🎓

Well I’m back. These videos taught me what I needed to know in AP Bio & now they’re helping me review with my college biology class!

me taking genetics in college and watching this to refresh my memory, thank you Professor Dave!!!

[Sara]

I’m in love with how you explained it! 😍 It’s really clear! THANK YOUUU!✌

[omwadhwani]

very nicely explained and
keep posting such videos.... thanks professor DAVE

thanks man i highly appreciate your contents

My textbook's diagram for cytokinesis was colored wrong. What I mean by that is the cytoplasm was tan with brown nucleus's, and it really looked like a *different part* of anatomy, even my mom noticed

He knows a lot about the science stuff ☺️☺️ thanks Prof

Watched: two copies of chromoses in the nucules, prophase spindle forms. meta phase nuclues breaks apart, metaphase chromosomes lines up on the metaphase plate, 4 ana phase shortsest phase enzyme cleaves the kohease, 5 telophase seperates the two and creates two nuclioties, mitosis is complete

[Traumbewusstsein]

Thank you, very clear and concise! What interests me is how did scientists found out about these processes. Was it all observed by microscopes? How do you observe something like a living cell with a microscope? What ideas were developed first, what model is still in need of further investigation?

A question for your next ask Dave video: How did you study back when you were an undergrad? Like your specific study routine. I'm looking to try new things since I'm making poor grades as a college freshman right now. Edit: Or it doesn't have to be in the ask Dave video, just a question in general.

I liked the explanation very nice and understandable!!

[shivapriya]

what happens to the mitochondria, golgi complex and ER during mitosis? Do they also split with the nucleus during metaphase?

[musicloverhayat]

You made me say woww😳😳 your videos are literally amazing.

[MikaCloudz.]

I have an exam tmr, you explained this better then my teacher did in 2 classes spanning 4 hours

[maddiesilvester]

Im kind of confused, in my textbook it says that the DNA is condensed during interphase into chromatin, but in the video I think he is saying that it becomes condensed at the start of mitosis (after interphase) - can someone pls tell me when the DNA is condensed and when it is not
